Hi All,
I’m using Solr 4.4.0 distro and now, I have a strange issue while
extending TokenizerFactory with a custom class.
This is an excerpt of pom I use:
<properties>
<solr.version>4.4.0</solr.version>
</properties>
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>*lucene*-core</artifactId>
<version>${solr.version}</version>
</dependency>
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>*lucene*-analyzers-common</artifactId>
<version>${solr.version}</version>
</dependency>
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>*lucene*-*queryparser*</artifactId>
<version>${solr.version}</version>
</dependency>
<dependency>
<groupId>org.apache.solr</groupId>
<artifactId>*solr*-core</artifactId>
<version>${solr.version}</version>
</dependency>
I always get the exception below during solr engine initialization:

What am I doing wrong? I‘ve already developed a lot of plugin in Solr
4.1 with success.
Is there another way to develop a plugin in 4.4 or later?
Thank you in advance.
Francesco
